Learner's Performance Evaluation based on Knowledge Extracting and Ontology

Learner’s Performance Evaluation based on Knowledge Extracting and Ontology

Test is one of the tools that are used to evaluate learner's achievement. Most of test scoring in e-learning systems are for true-false and fill in blank questions. Description questions are human efforts and time consuming. A courseware with its questions bank had been built based on ontology. Extracting the semantic keywords from the learner's answer would be used to score the answe...

Performance evaluation of ontology based Information Retrieval

Main objective of this paper is to achieve personalization of information retrieval activities. Personalised retrieval effectiveness is defined in terms of retrieving relevant documents and not retrieving nonrelevant documents. Two traditional factors of measuring effectiveness are Recall and Precision are focused upon. Based on these two factors the effective performance of Ontology based retr...

PRONTO - Ontology-based Evaluation of Knowledge Based Systems

In this paper we examine some of the ways in which an ontology can be used to assist in the evaluation of knowledge-based systems. Key elements of the support provided by the ontology relate to attempting to give coherence to the domain conceptualisation; making the role of experts in evaluation more structured and less at the mercy of interpretation; constraining the number of test cases requi...
